Black/ Green PTFE/ FPM + EPDM Rubber Valve Nofo mo Butterfly Valve Nofo
PTFE + EPDM faʻapipiʻiina nofoa valve paʻu gaosia e SML o loʻo faʻaaogaina lautele i le ie, eletise, petrochemical, faʻamafanafana ma le pusaaisa, vailaʻau, fau vaa, metallurgy, alamanuia mama, puipuiga o le siosiomaga ma isi fanua.
Fa'atinoga o oloa: maualuga le vevela, malosi lelei ma le alkali ma le suau'u; fa'atasi ai ma le toe fa'aleleia lelei, malosi ma tumau e aunoa ma le tafe.
PTFE+EPDM
O le liner Teflon (PTFE) e ufiufi ai le EPDM lea e fa'apipi'i i se mama phenolic malo i luga o le pito nofoa pito i fafo. O le PTFE e faʻalautele i luga o le nofoa faʻailoga ma fafo o le faʻamaufaʻailoga faʻamaufaʻailoga, e ufiufi atoa ai le EPDM elastomer layer o le nofoa, lea e maua ai le maufetuunaʻi mo le faʻamaufaʻailoga valve stems ma le tapuni tapuni.
Vevela Vallow: - 10 ° C i le 150 ° C.
Taupou PTFE (Polytetrafluoroethylene)
PTFE (Teflon) o le fluorocarbon faʻavae polymer ma e masani lava o le sili ona faʻamaʻiina faʻamaʻi mai palasitika uma, aʻo faʻatumauina mea lelei faʻavela ma eletise. O le PTFE e iai foʻi le maualalo o le feteʻenaʻiga o lea e lelei mo le tele o faʻaoga maualalo.
O mea nei e le fa'aleaga ma talia e le FDA mo mea'ai. E ui lava o mea faʻainisinia o le PTFE e maualalo, faʻatusatusa i isi palasitika faʻainisinia, e tumau pea lona aoga i luga o le lautele o le vevela.
Vevelation stress: - 38 ° C i + 230 ° C.
Lanu: paepae
Fa'aopoopo fa'asili: 0%

O lo tatou tumaoti Badterfly Atord Cours o le Tutuutu o le Faʻailoga o le Tatou Line Way, ua fuafuaina mo le faʻaaogaina i le Matagofie, suauu, kesi, ma e oʻo foi i faʻasalalauga o asoa. O loʻo tuʻuina atu i latou e faʻataʻitaʻi e sili atu i le maualuga o le sipelatia o le vevela - Ma le lapoʻa o le fuafuaina mai le DN50 i le DN600, o matou faʻamau o loʻo tuʻufaʻatasia ma mafai ona tuʻufaʻatasia i ituaiga eseese o vanu o valevale e aunoa ma se mea. I tala atu o a latou galuega aoga, o nei faʻailoga o se molimau i le faʻamaoni o Sawsheng fluscerine plastics i le lelei ma le gafataulimaina. Faʻatinoina se gaioiga tulaga ese o loʻo tuʻufaʻatasia e fesoʻotaʻi ai le vailaau o le ptfe ma le manaia ma le tumau o le OPDM, o le sili atu le fiafia, ma le saogalemu. Ua latou mauaina o latou nofoaga i vasega leaga pei ona taua, eletise, o gaioiga pefulele, moli, moli eletise, ma lautele lautele, ma lautele lautele Faʻatasi ai ma le matou fale puipui o le alatoto alatoto, e te le naʻo le faʻatauina o se oloa; Oe teuina i le filemu o le mafaufau, iloa o au gaioiga e faamaufaailogaina ma le silisili.
